New paper on Y chromosome haplogroup T

The occurrence in Europe of lineages belonging to both T1a1 (old T1a) and T1a2 (old T1b) subclades probably reflects multiple episodes of gene flow. T1a1* haplogroups in Europe likely reflect older gene flow.
The presence of T1a2 chromosomes in Near Eastern Jewish and non-Jewish populations may reflect early exiles between the ancient lands of Israel and Babylon. The presence of different subclades of T chromosomes in Europe may be explained by both the spread of Neolithic farmers and the later dispersal of Jews from the Near East.
